Structural Basis of GABAB Receptor Activation during Evolution

Advanced Science, EarlyView.
This study explores the structural and functional mechanisms of the drosophila GABAB receptor, a key role in neurotransmission. Using cryo‐EM, the research reveals how the receptor's activation differs from its human counterpart, highlighting unique evolutionary features.

Antipsychotic profiles of TASP0443294, a novel and orally active positive allosteric modulator of metabotropic glutamate 2 receptor

Journal of Pharmacological Sciences, 2015
Glutamatergic dysfunction has been implicated in psychiatric disorders such as schizophrenia. The stimulation of metabotropic glutamate (mGlu) 2 receptor has been shown to be effective in a number of animal models of schizophrenia.

Genome‐Wide Insights and Polygenic Risk Scores in Common Epilepsies: A Narrative Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT The research of single gene‐related disorders or pathogenic copy‐number variations (CNVs) has given a significant impetus to the shift from a diagnostic work‐up focused on epileptic syndromes to genomic approaches in individuals with severe pediatric‐onset epilepsies and in developmental and epileptic encephalopathies.

Developing HaloTag and SNAP‐Tag Chemical Inducers of Dimerization to Probe Receptor Oligomerization and Downstream Signaling

Angewandte Chemie International Edition, Accepted Article.
Controlling protein‐protein interactions is critical for dissecting signaling pathways, especially those initiated by ligand‐receptor interactions which alter receptor oligomerization and drive downstream signaling cascades. Traditional methods for driving protein‐protein complexes are using antibodies that face limitations in terms of stoichiometry ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

First evidence for the presence of amino acid sensing mechanisms in the fish gastrointestinal tract

Scientific Reports, 2021
This study aimed to characterize amino acid sensing systems in the gastrointestinal tract (GIT) of the carnivorous fish model species rainbow trout. We observed that the trout GIT expresses mRNAs encoding some amino acid receptors described in mammals ...

Fathoming the kynurenine pathway in migraine: why understanding the enzymatic cascades is still critically important [PDF]

, 2015
Kynurenine pathway, the quantitatively main branch of tryptophan metabolism, has been long been considered a source of nicotinamide adenine dinucleotide, although several of its products, the so-called kynurenines, are endowed with the capacity to ...

Diverse Subpopulations of Reactive Astrocytes Following Chronic Toxoplasma Infection

Glia, EarlyView.
Toxoplasma infection results in distinct astrocyte subpopulations. Chronically labeled reactive astrocytes appear transcriptionally plastic and can regain acute inflammatory responding and naive homeostatic astrocytic gene patterns in the presence of ongoing neuroinflammation.

Conformational diversity in class C GPCR positive allosteric modulation

Nature Communications
The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate.
